    "options": [
      "-Xms2048m",
      "-XX:+UseG1GC",
      "-Xmx4096m",
      "-XX:ReservedCodeCacheSize=512m"
    ],
    "correctAnswerIndex": 2,
    "explanation": "文档中提到，在`ts-api`项目中，团队通过将JVM的最大堆内存（-Xmx）调整为4096MB，解决了IDEA频繁崩溃的问题。-Xmx参数直接定义了IDEA可以使用的最大内存量，当内存不足时，增加此值是首要的解决方案。-Xms是初始堆内存，-XX:+UseG1GC是垃圾回收器，-XX:ReservedCodeCacheSize是代码缓存，虽然都与性能相关，但最大堆内存是解决内存溢出或崩溃最直接的参数。",
    "source": "文档中「2.1 调整 JVM 参数」和「4.2 在 ts-api 项目中调整 JVM 参数」部分",
    "hint": "文档中有一个实际项目案例，通过修改一个与“最大”内存相关的参数解决了崩溃问题。"
  },
  {
    "question": "在处理一个包含大量前端依赖（如`node_modules`目录）的项目时，文档推荐了哪种方法来显著减少IDEA的索引时间，从而加快启动和响应速度？",
    "options": [
      "启用 Power Save 模式",
      "将`node_modules`目录标记为 `Excluded`",
      "清理缓存并重启 (Invalidate Caches / Restart)",
      "增加 -Xmx 参数的值"
    ],
    "correctAnswerIndex": 1,
    "explanation": "文档明确指出，通过在项目设置中将不需要索引的文件和目录（如`node_modules`和`dist`）标记为`Excluded`，可以有效优化索引，减少资源占用。`ts-web`项目的案例也证明了这是减少索引时间的有效方法。其他选项虽然也是优化手段，但不是针对特定目录索引问题的最直接解决方案。",
    "source": "文档中「2.2 优化项目索引」和「4.1 在 ts-web 项目中优化索引」部分",
    "hint": "想一想如何告诉IDEA“不要理会”某些特定的文件夹，以减轻它的工作负担。"
  },
  {
    "question": "IntelliJ IDEA的“Power Save Mode”（省电模式）会带来什么主要效果？",
    "options": [
      "它会自动禁用所有第三方插件，只保留核心功能。",
      "它会禁用一些耗电和消耗资源的后台功能，如代码检查和自动完成，从而提升性能。",
      "它会强制清理所有项目缓存和索引，释放磁盘空间。",
      "它会降低编辑器的屏幕亮度和色彩对比度以节省电量。"
    ],
    "correctAnswerIndex": 1,
    "explanation": "根据文档描述，Power Save模式旨在通过禁用一些耗电功能来提升性能。这通常包括关闭实时的代码检查、代码提示和后台任务，从而减少CPU和内存的消耗。它不会自动禁用插件或清理缓存，其主要作用是减少后台活动。",
    "source": "文档中「2.5 使用 Power Save 模式」部分",
    "hint": "这个模式的名称暗示了它的目的。它通过“节省”什么来达到目的呢？文档中提到它会“禁用一些耗电功能”。"
  },
  {
    "question": "文档提到了多种导致IntelliJ IDEA性能下降的原因。以下哪一项不属于文档中明确列出的原因？",
    "options": [
      "安装了过多的插件",
      "项目规模过大，文件和依赖繁多",
      "硬件的CPU或内存性能不足",
      "网络连接不稳定或速度过慢"
    ],
    "correctAnswerIndex": 3,
    "explanation": "文档在“1.2 性能问题的原因”部分列举了四个主要原因：项目规模过大、插件过多、配置不当和硬件限制。其中并未提及网络连接状况是导致IDEA本身性能下降的直接原因。",
    "source": "文档中「1.2 性能问题的原因」部分",
    "hint": "请回顾文档第一章节中关于性能问题原因的列表，看看哪个选项不在其中。"

    "question": "如果一个开发者不使用IntelliJ IDEA内置的数据库客户端功能，根据文档的建议，禁用哪个插件可以帮助提升IDE的响应速度？",
    "options": [
      "CVS Integration",
      "Database Tools",
      "GitHub",
      "Git Integration"
    ],
    "correctAnswerIndex": 1,
    "explanation": "文档在“禁用不必要的插件”部分和“在 ts-mobile 项目中禁用插件”的案例中，都明确将`Database Tools`作为一个可以禁用的插件示例，特别是在不使用数据库工具的情况下，这样做可以提升IDEA的响应速度。",
    "source": "文档中「2.3 禁用不必要的插件」和「4.3 在 ts-mobile 项目中禁用插件」部分",
    "hint": "文档通过一个移动项目的实例，具体指出了一个与数据库相关的插件可以被禁用。"
  },
  {
    "question": "对于IDEA强大的代码检查（Inspections）功能，如果它消耗了过多资源导致卡顿，文档提供了哪种优化建议？",
    "options": [
      "只在提交代码前手动触发代码检查",
      "将检查级别从`All Problems`调整为`Syntax`",
      "卸载并重新安装代码检查插件",
      "使用 `File > Invalidate Caches` 来重置检查引擎"
    ],
    "correctAnswerIndex": 1,
    "explanation": "文档在“调整代码检查设置”一节中提出了两种优化方法：一是禁用不必要的检查规则，二是降低检查级别。将检查级别从全面的`All Problems`调整为只检查基本语法的`Syntax`，可以极大地减少资源消耗。",
    "source": "文档中「2.4 调整代码检查设置」部分",
    "hint": "文档中提到了两种优化代码检查的方法，其中一种涉及调整检查的“严格”程度。"
  },
  {
    "question": "在什么情况下，开发者应该使用 `File > Invalidate Caches / Restart` 这个功能？",
    "options": [
      "当需要快速切换到另一个项目时",
      "当IDEA的缓存和索引随时间推移变得臃肿，可能导致功能异常或性能下降时",
      "当修改了`.gitignore`文件后，为了让规则立即生效",
      "每次启动IDEA前都应执行一次，以保证最佳性能"
    ],
    "correctAnswerIndex": 1,
    "explanation": "文档指出，“IDEA的缓存和索引可能会随着时间的推移变得臃肿”，这时可以通过`Invalidate Caches / Restart`来清理它们。这是一个修复由缓存损坏或过时引起的奇怪问题或性能瓶颈的常用方法，但不应作为日常操作。",
    "source": "文档中「2.6 清理缓存和索引」部分",
    "hint": "这个功能的名字“Invalidate Caches”本身就说明了它的用途，主要用于处理“缓存和索引”可能出现的问题。"
